TEMPORARY BINDER.

Application filed September 3, 1907.

To all whom it may concern} Be it known that I, O'rro'I-I. SorrRAnGnR, :a citizen of the United States,1residing at Kalamazoo, Kalamazoo; county, Michigan, have invented certain new and useful Improvements in Temporary Binders, of which the following is a specification.

This invention relates'to improvement-s in temporary binders. or loose sheet holders.

The main objects of this invention are, first, to provide an improved temporary hinder or loose sheet holder in which the formed of sheet metal; second-,to provide an improved temporary binder for'loose sheet holders in which the binding mechanism is formed of'sheet metal, which may be of comparatively light weight, and at the same time one which is very strong and durable; third, to provide an improved. temporary binder or loose sheet holder which is very quickly and easily adjusted; and fourth, to provide an improved temporary binder or loose sheet holder which is very economical to produce.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. V j

The inventionis clearly defined and pointed out in the claims. i

A structure embodying the features of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which,

Figure 1 is a detail inside view of a structure embodying the features of my invention with the covers extended or open, portions being broken away to show the arrangement of the parts; Fig. 2 is a detail longitudinal a line corresponding to line 2-2 of Fig. 1; 3 isa detail transverse section taken on aline corresponding to line 3-3 of Fig. 2 Fig. a is an end elevationof the binding or back portion; Fig. 5 is an en larged. detail section thereof taken on a line corresponding to line 5-.5 of Figfid; Fig. 6- is a detail inside view of a modified structure; Fig. 7 is a detail end elevation of the structure appearing in Fig. 6; Fig. 8 is a longitudinal section, taken on a line corre sponding to line 88of Fig. 6; Fig. 9 is an taken on the broken'line 9 9, is an enlarged detail a line corresponding to of Fig. 6; and Fig. 10

. In the drawing, the sectional views are taken lookingin the direction of the little arrows at t e ends of the section lines, and similar numerals of reference refer to similar parts throughout the several views.

Referring to the drawing, the back pieces 1 are formed of sheet metal and are provided with forwardly-projecting flange-like end portions 2. These backs and ends are adapted to telescope upon each other. The

ends of one of the back pieces are provided wvith longitudinal slots 3 adapted to receive ends of the other the screws at carried bythe Figs. 1 and 5. The screws 4 back piece see are provided with suitable nuts 5 which may be turned up to secure the parts adjustably together. I V

he posts 6 are formed integrally with theback pieces by folding the back pieces upon themselves, as clearly appears from Fig. 3. I preferably provide T-shapedposts illustrated, although it will be obvious that any shaped posts desired can be secured by this means. The posts of one back piece are arranged to telescope within the posts of the other,- thus forming adjustable binding posts for the sheets or leaves to be: secured by the binder.

The back pieces 1 are provided with flange-like clamping members 7, which are also formed integrally therewith. The ends of the clamping members are preferably theend pieces 2 and secured thereon by soldering or brazing, thereby eflectively supporting the end pieces as comparatively light material, the one part serving as a brace or support for the other.

., he clam ain members are referabl provided with bead-like hinge members or 9 on, their inner. edges adapted to receive the hinge pivots 10 for securing the covers. These hinge pivots are preferably formed'of wire and are provided with arms 11 to which the covers 12 are secured. The

covers ,arepreferably made up of layers,

as illustrated, so that the arms 11 may be I or secured between the same; see Figs. and 2. By this simple means, I thus effectively secure the covers, and at the said back pieces, the ends of said clamping same time the cover connection is a very economical one.

In the modified construction shown in Figs. 6 and 10, the post members 6 are formed on the ends of the backs instead of and covers secured to the said arms of said intermediate the ends, as in the construction pivot members. shown in Figs. 1 to 5, inclusive, and a posi- 2.

This arrangement proslotted; screws carried by the end pieces of vides a chamber at the rear of the posts for the other back piece adapted to engage said the adjusting mechanism, which preferably slotted end piece; thumb nuts for said screws consists of the screw 23 journaled in bearwhereby said back pieces are adjustably ings l5 and 16 at each end of the screwsecured together; binding posts arranged This screw is reversely threaded and is protransversely of said back pieces and formed vided with a pair of nuts 17, which are prointegrally therewith by folding the said iClGCl With perforated ears to receive the back pieces upon themselves, the binding links 18. These links are crossed and conposts of one of said back pieces being adaptnected by the ears 19 to the back members.
